About this 3D model

This is a 3D printed piece that works as an interconnect between the large variant of plastic building bricks for toddlers and common wooden train tracks. I was inspired by http://www.thingiverse.com/thing:4041 , but after trying out a print, I found it too difficult for the 3 year old to put the tracks on, and I decided to make my own, slightly simpler design. It's designed in OpenSCAD and I have uploaded the .scad file along with the .stl file, so that you can easily modify as needed Instructions There are two different versions in this project: The original, designed for the BRIO train tracks Updated version, adjusted for the IKEA LILLABO tracks, that seems to have a slightly shorter neck on the connecting part
